"Seeing a doctor?" Tang Yuran was stunned for a moment, then asked with puzzled eyes, "What happened to Gu Yu?"
"Mom doesn't know either." Tang Yuran's mother reached out and stroked her head, saying, "It was quite noisy on the other end of the phone, and the signal wasn't very good. Gu Yu's mother seemed pretty anxious, so I didn't feel it was right to ask too many questions."
"So, does that mean we can't go to Gu Yu's house to play today?" Tang Yuran looked up at her with expectant eyes.
